giving the probability \(P\)  that \(N\)  points fall in volume \(V\) , when the
event rate is \(\lambda \)  events per unit volume. The usual derivation of
this formula as the limit of repeated Bernoulli trials
[1]} has led to a common misunderstanding
that it is fundamentally an approximation, but the above equation is
exact – absent correlations of the sort discussed above.
